Changing BIOS RAID Configuration

Hi Experts,

I recently got the support of an HP Proliant ML 150 G5 and I would like to ask you some questions:

1. First of all I would Like to ask if by alter that BIOS settings for disk configuration makes the data to be lost. I want to do that because the Array Configuration Utility does not recognize my controller. The controller is the default SAS/SATA Hot plug Controller

2. The second thing is that I'm getting messages for bad blocks within the Windows Event Viewer. Any suggestions on how to handle this? As a note, on of the two disks of the RAID 1 configuration has failed and today a new one will arrive. The disk are hot pluggable so I guess by putting the disk in the controller it will automatically start the rebuild... (?)
